Forced to cancel his visit to Smith in Norwich following "sudden and unexpected" death of his father-in-law. Thanks Smith for agreeing to value the eleven volumes of [Sir Edward] Coke's papers [(1552-1634), lawyer, legal writer, and politician, ancestor of Thomas William Coke, to whom he sold the papers]. Pleased to learn from Smith's former letter that [William] Roscoe's prospects have improved [Roscoe was declared bankrupt in 1816], though sorry his library could not be saved.
